SubjectPATCH 9/19] serio manual bind
Date

===================================================================


ChangeSet@1.1783, 2004-06-27 15:56:35-05:00, dtor_core@ameritech.net
Input: allow marking some drivers (that don't do HW autodetection)
as manual bind only. Such drivers will only be bound to a
serio port if user requests it by echoing driver name into
port's sysfs driver attribute.

Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
